Are you sure it isn't the motion ?
A little bit of tweaking with the tweasers should make it go away IE increase the clearance for the rods. You arnt alone however read below.

Last night, the monthly open running night on our 00-Gauge layout. One
of the rare times when taking along one's own locomotives is positively
encouraged. The layout is basically a commercial undertaking and 'own
stock' running at other times is actively discouraged.
First out of the box a Hornby 4-6-0 Class 5MT which ran approximately
two 120ft circuits before the right hand cylinder jammed up at about
half speed, seized solid and scrambled up the running gear. Owner
ruefully said that it ran on test in the shop quite happily [for 4ft
twice].
Next out of the box a very nice airforce grey 'Pacific' [limited
addition - the grey wheeled job], This loco was also experiencing its
first real run, in fact its only known run as it was supplied by mail
order and possibly had not been supplier tested. It ran just one circuit
before the RH side running gear partially locked up and before the loco
stopped the con rods had twisted and mangled themselves up beautifully.
A real Hornby demolition derby. Both these locos had original prices on
the boxes, the black five £86.00. Quite expensive rubbish.
An appalling display of some of the trash currently available on the UK
model scene. Incidentally this type of quite common problem is one of
the reasons that we as a group discourage 'own stock' running while the
layout is open to public. Watching a loco derail while hauling 30+ goods
waggons with eight locos running is not funny. This of course only
happens when the place is heaving with spectators :0)
I will admit however that some of us watched this display with
considerable amusement. We run German and East European locomotives only

A widespread problem usually caused by careless handling of the loco - i.e.
the valve gear being 'grabbed' rather than the model being handled properly.
I'm not suggesting that it should bend so easily, but it does - Bachmann's
valve gear doesn't have this problem.
We've reported the problem to Hornby on numerous occasions, but they never
respond. We now send all such locos back to them when this fault occurs,
and whilst they happily repair or replace the fault, it strikes me that they
don't comprehend that the models are not up to the slightest bit of rough
handling.
Send them back to where your friend got them from and ask for them to be
repaired or replaced and for your postage to be refunded. That's all I can
suggest.
